Isaiah 29:10-12

For the LORD has poured out on you The spirit of deep sleep, And has closed your eyes, namely, the prophets; And He has covered your heads, namely, the seers. The whole vision has become to you like the words of a book that is sealed, which men deliver to one who is literate, saying, “Read this, please.” And he says, “I cannot, for it is sealed.” Then the book is delivered to one who is illiterate, saying, “Read this, please.” And he says, “I am not literate.”
